We're not a round-the-clock dispatch service.
Business-hours calls are returned within 24 hours, and we aim to be on site the same or next business day. True emergencies are different: no heat in freezing weather, no water to livestock, active flooding, or no A/C in extreme heat. Call 519-506-3834 and leave a message any time, and we will respond.
If you smell gas: leave the building, call your gas utility from outside, then call us. Do not relight a pilot.
If water is actively running: shut off the main valve at the meter or street if you can. Then call.
A few things that make it worse.
The fastest, cheapest fix is almost always avoiding the move that broke the thing in the first place.
Don't pour chemical drain cleaner
Caustic drain cleaners eat the inside of your pipes (and your plumber's skin). They rarely solve the real problem. Call us with a clogged drain and we'll camera it instead.
Never relight a pilot if you smell gas
If you smell gas in your home, leave the building, call your gas utility from outside, and then call us. Do not flip switches, do not relight pilots, do not hunt for the source.
Don't run an iced-up AC
If the outdoor unit or the indoor coil is iced up, running it makes it worse. Shut it off, let it thaw fully, and give us a call to find the underlying cause.
Don't ignore a slow leak
Small drips become rot, mould, and ceiling repairs faster than people expect. Even a leak under a vanity is worth a same- or next-day visit.
What to do until we get there.
Each section covers what you can safely check or shut off before we arrive.
- Locate and shut off your main water valve immediately if a pipe has burst or there is a major uncontrolled leak.
- For an isolated leak under a sink or at a toilet, turn off the individual supply valve at the base of the fixture. No need to shut off the whole house.
- If a toilet is overflowing, turn the valve at the base of the toilet clockwise to stop water flow, then place towels to contain any overflow.
- Do NOT use store-bought drain cleaning chemicals. They can damage pipes and may make the blockage harder for us to clear safely.
- For a water heater that is leaking, turn off the cold-water supply inlet and switch off the power or gas to the unit at the source.
- If you suspect a frozen pipe, do NOT use an open flame or heat gun. A hair dryer on low heat applied gently from the faucet end toward the frozen section is the safest approach.
- If your sump pump fails during heavy rain or snowmelt, move valuables and important items off the basement floor immediately while you wait for service.
- Turn off water supply valves to appliances (dishwasher, washing machine) if they are connected to a leaking line.
- Do not flush anything other than toilet paper: no wipes (even "flushable" ones), paper towels, or sanitary products.
- Take photos or a short video of the issue and note when it started. This helps us diagnose and arrive prepared. Email video to general@kdgplumbing.com.
No water to the barn is a true emergency
Agricultural customers: if livestock has no water, that is a true emergency. Call and leave a message any time and we will respond.
- Check your thermostat first: confirm it is set to "Heat" mode and the temperature is set above the current room temperature.
- Check the circuit breaker or fuse for your furnace, boiler, or heat pump. A tripped breaker is one of the most common causes of a no-heat call.
- If you smell gas at any time, do not touch any switches. Leave the building immediately and call your gas utility's emergency line from outside.
- Check your furnace or air handler filter. A severely clogged filter can cause the system to shut down on a safety limit. Replace it if it looks grey and dense.
- For hydronic/boiler systems, check the pressure gauge on the boiler. It should read between 12 and 15 PSI when cold. If it reads zero, the system may have lost water.
- Note any error or fault codes displayed on your furnace or boiler control panel and write them down. These codes tell us exactly what triggered the shutdown.
- Keep interior doors open to allow heat to circulate from any rooms that are still warm.
- If temperatures will drop overnight, prepare a backup heat source (e.g., an approved electric space heater) and let a faucet trickle slightly to prevent pipes from freezing.
- Do not attempt to relight a pilot light if you smell gas or are unsure of the procedure. Wait for our technician.
- For wood boiler or wood stove systems, ensure the firebox has adequate fuel and the flue damper is properly open before assuming the system has failed.
Viessmann boiler owners
Your Viessmann shows the system pressure and an error code right on its display. Leave a message with the pressure reading and the error code so we know how to help before we arrive.
- Check the thermostat: confirm it is set to "Cool" mode, the fan is set to "Auto" (not "On"), and the set temperature is below the current indoor temperature.
- Check the circuit breakers for both the indoor air handler and the outdoor condenser unit. These are often on separate breakers.
- Inspect and replace your air filter if it is dirty. A clogged filter is the single most common cause of AC underperformance and freeze-ups.
- Check the outdoor condenser unit: clear away any leaves, grass clippings, or debris that may be blocking airflow around the unit.
- If the indoor coil or outdoor unit is covered in ice, turn off the "Cool" mode but leave the fan running on "Fan Only" to thaw the ice, typically 2–4 hours. Do not run cooling again until fully thawed.
- Check around the indoor unit (furnace/air handler) for water pooling. This can indicate a clogged condensate drain line. You can try pouring a cup of water into the drain pan to test flow.
- Do not run the AC if it is making unusual grinding, banging, or screeching sounds. Turn it off and call us to avoid further damage.
- Keep blinds, curtains, and shades closed on sun-facing windows during peak afternoon hours to reduce the heat load on your system.
- Limit heat-generating appliances (oven, dryer, dishwasher) during the hottest part of the day to reduce the strain on your cooling system.
- Use ceiling fans or portable fans to circulate air. The wind-chill effect makes rooms feel cooler without lowering the thermostat.
What the office hears most often.
The everyday questions from the phone.
For residential plumbing and HVAC, we cover the Grey-Bruce core: Hanover, Walkerton, Chesley, Durham, Priceville, Ayton, Mildmay, Teeswater, Tiverton, Kincardine, Glammis, Saugeen Shores, and the surrounding area.
For commercial, ICI, and hydronic specialty work, we travel further across Southern Ontario: Mitchell, Barrie, Essa, Wasaga Beach, and further for the right job. Get in touch if you're not sure.
Phone calls during business hours get a callback within 24 hours, and we typically have someone on the job the same business day or the next. For non-business-hours calls, you'll hear back the next business day.
For true emergencies, see the emergency section at the top of this page.
Both. We split the work into two sides of the business: residential plumbing and HVAC across Grey-Bruce, and commercial, ICI, and hydronic mechanical work for the wider region. See Residential Services or Commercial Services for the full list.
For boilers and hydronic, Viessmann. For fireplaces and wood stoves, Pacific Energy. For furnaces, AC, and water heaters, we install and service the major brands. Just ask us about a specific make.
Yes. New-home plumbing we install carries a two-year warranty on our workmanship. Manufacturer warranties on installed equipment (Viessmann, Pacific Energy, AC and furnace units) are passed through, and we handle the warranty service in-house.
Two ways, and we respond to both: call us at 519-506-3834, or fill out the request form. Give us the address, what's happening, and the best number to reach you on.
Not yet. We focus on the job in front of us. If you'd find a maintenance plan useful, let us know; it's on the consideration list.
No, we don't offer financing.
Yes. Kyle is a licensed plumber and gas technician; the team holds AC and refrigeration, sheet-metal, and WETT certifications; and the company carries insurance and bonding for commercial and tender work. The full credential list is on the About page.
Hanover, Ontario, in the Grey-Bruce region. The company has run out of Hanover since 2019.
